CAR-DOOR CLOSURE.

Specification of Letters Patent.

Patented Sept. 20, 1910.

Application filed January 17, 1910. Serial No. 538,509.

To all whom it may concern:

Be it known that I, ARTHUR FAGET, citizen of the United States, residingat San Francisco, in the county of San Francisco and State ofCalifornia, have invented a new and useful Car-Door Closure, of whichthe following is a specification in such full and clear terms as willenable those skilled in the art to construct and use the same.

Thisy invention relates to an apparatus for the purpose of precoolingthe air in refrigerator cars, the object being to reduce the temperatureof the air in the car, together with the contents thereof, to thedesired temperature, prior to the shipment of the materials. It will beunderstood by those familiar with the art that it requires someconsiderable time to reduce the temperature of fruit and otherperishable articles, to suitable temperature for transit, if thematerials are simply placed in the car and ice supplied to the bunkers.The disadvanta e of this is that from three to live days e apse beforethe desired low temperature is attained, during which time more or lessdecay may take p ace.

The apparatus illustrated and described in this specification isintended for the purpose of handling the air used in precooling the carand contents, and the particular object of the invention is todistribute the cold air in the car in such a manner as to prevent injuryto the materials to be cooled.

In precooling the car and contents, air is used as cold as the articlesto be cooled will ermit that is with an ordinar refrigera- P a a o tionplant, say from freezing to several degrees below zero, the object beingto detain the car as short a time as possible, and to cool the fruit toa temperature of about 40 Fahr. in as short a time as possible. Sincethis air is so cold, it would freeze any fruit or other perishablevegetables very quickly if allowed to strike the same directly. Ittherefore becomes necessary to provide means for diifusing the cold airin such a manner as to completely cool the air in the car together withthe contents thereof, while at the same time preventing the cold airfrom the refrigeration plant from striking the fruit or vegetables.

In the drawings, in which the same numeral of reference is applied tothe same portion throughout the several views, Figure l illustrates acentral vertical sectional view through one of the car door plugs, and

a portion of a car the pipe 8 being shown in full lines; Fig. 2represents a front elevation of a portion of a car and one of the plugs;Fig. 3 represents a horizontal sectional view of one of the plugs and aportion of the car on a larger scale than Fig. 1; Fig. 4 is a plan viewof a portion of a car, and one of the hatchway lugs; and Fig. 5 is avertical sectional view of the plug shown in Fig. 4 on the line 5 5thereon.

The numeral 1 is applied to the car body, and 2 represents the side wallof the car, the said wall of the car being provided with doors 3-3- Thedoors are opened and a plug f -t is inserted in the door opening, saidplug having pneumatic tubes 5 to make a tight joint with the door jamb,lintel and sill. Near the upper portion of the plug there is a box-likecaslnfr G, supported by means of braces 7 into which an air-pipe 8leads. The side of this plug next the car contents is provided with twocross-bars 9 and 10, said bars supporting a curved plate 11, whichextends to the bottom of the box 6, and against which the air from thepipe 8 impinges on entering the car. This curved plate causes the air tobe deflected npwardly, Iand in order that it may be properly distributedin the car, four other curved plates 12, 13, 14 and 15, are connectedwith the plate 11. These four plates are curved laterally, and arestraight vertically. The plates 13 and 14 are connected at 1G, and forma curved wedge, while the plates 1Q and 15 are spaced away from theplates 13 and 14., and are substantially parallel therewith. The resultof this construction is that the air passing through the pipo 8 in thedirection of the arrow, strikes the plate 1l, is directed upwardly, andis spread out in the shape of a fan by means of the plates 12 to 15, thebody of the air forming the fan extending in the neighborhood of the carroof, and away from the car contents. Where convenient, other plugs willbe connected with the hatchways of the car and the air will be passed inthrough pipes 8 and within the car through the hatchways thereof. Butunder certain circumstanfws, it may become necessary to reverse thecurrent of the air, and since it is not desirable to change the carequipment, since there are great numbers of standard refrigerator cars,having a given equipment, a plug such as is shown in Figs. 4 and 5 maybe used. In this case the plug is provided with means for makingl atight joi-nt With the hatchvvay of the car, substantially like the meansshown in Figs. l to 3. The numeral 18 represents the car roof, 19 therunning board near the center of the car, and 20 the rim of thehatchway. In this hatchvvay is inserted the plug 21, having the air pipe22 secured thereto by means of a flange 23, rings 24: being provided fortheconvenienthandling of the hatchway plug. Since the course of the airthrough the pipe 22 is directly down...

securing a series of three curved plates 25,.

26 and 27 to the hatchvvay plug at` the bottom of the pipe 22. Then, asthe air passes into the car through the pipe 22, it will be.

- driven in the path indicated by the bottom of the curved' plates, thusspreading and diffusing the cold air in the car close to the roof, andpreventing injury to the car contents.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent of the .United States, is as follows:

1. In a plug for car doors, a frame, means to make said frame air-tightin a door opening, an air pipe connected With said frame,

and deflecting means interposed in the path of the air to direct the airtoward the roof of a car, as described. Y

2. In a plug for car doors, a frame, means to make said frame airetightin a door opening, an air pipe connected with said frame, and deflectorsarranged in the frame at the end of said pipe so as to direct the air ina fan-shaped body toward the roof of acar, substantially as described.

3. In a plug` for car doors, a frame, means to make said frame air-tightin a door open-y ing, an air pipe connected with` said frame, anddeflecting means interposed in the path of the air to. direct the airtoward the roof -of a car, and comprising a series of curved platesadapted to spread the air into a fanshaped body near the roof of a car,as set forth.

4. In a plug for car doors, a frame, means to make said frame air-tightin a door opening, and an air pipe connected With said'VA ARTHUR FAGFET.
